All participants received hepatitis B testing: HBsAg (hepatitis B surface antigen), HBsAb (hepatitis B surface antibody) and, HBcAb (hepatitis B core antibody). A total of 600 completed the survey and screening. A week later, they received the results of the screening test. Based on the screening results, all participants were categorized into three groups: (1) infected (HbsAg+), (2) unprotected (HbsAg-/HbsAb-), or (3) protected (HbsAg-/HbsAb+). We sent the results by mail to participants who were unprotected and protected. Among those 600 screened participants, 33(5.5%) had chronic hepatitis B virus (HBV) infection and 335 (55.8%) had evidence of resolved HBV infection (protected). A total of 232 (38.7%) were susceptible to HBV infection (unprotected).
